IMPROYEMENT IN LIQUIDMETERS.

Be it known that I, CHARLES II'. R'IGGS, of Warwiek, in the 'county of Orange, and State of New York,

have invented a new andimprovedAutomatic- Liquid-Meter;` and I 'do hereby declare that the followingris a full, clear, and exact description thereof, which -will enable those skilledjn the artto make and usc the same, reference being had to thcsaiccom'panying drawings; forming partfof this specification, in whch- Figure 1 isla 'front view'of my improved meter.

Figure Z-s a section ofthe same, through the line x x, iig. 1.

Figure 3 is a diagram view, showing the metier-tank receiving.

Figure 4 is a similar view, showing the meter-tank discharging'.

Similar` letters of reference indicate.corresponding par-ts. g

This .invention refers to the automatic measurement of liquids, and consists of the mechanism-now to be shown and described. l v v n e v AIn the description, the measurement of water will be considered, the operation being the same for al1 liquids.

In the drawings, A is the' body er box containing vthe"n,1echanism, and forming part of the meter-taullfB.`

G-is" thel receiving-pipe, which conveys the 'water tc lie-measured; Itdschhargesinto a small receivingcistern, D, from whence the water is discharged by the Siphon E into the meter-tank, when it has risen to a certain height in the said cistern.

The ebject. of thiscistern is to receive the first flow of water incase the same enters before the meter-tank is entirely emptied;

When the water has riscn'to a certain determined height in the. meter-tank, the -Siphon F fills and draws oli' the water from the meter-tank, until tht-:level ofthe said water reaches the bottom of the short leg ofthe siphon, which will thus be a certaindenitequantity of water.

The. receivingpipe C- is opened und closed by a. sto'p-valve or gate, d, forming part of the lever b, which is actuated by certain float-mechanism to open and close the said pipe, when the water in the meter-tank'has attained certain determined levels, whereby a deti'nite quantity of water is discharged at each operation.

` The operation ef this iioat-mechariismwill now be described.v i l The oat' I is connected with the gate-lever. b by the rod z', lever q, and link p, as shown, and the-other oats, G and IL-arc themeans whereby the iloat I is disengaged from either one of the two positions, when the metertankvis filled or emptied.' j v When thetank B is being filled, as shown at, iig. 3, the float I is in its lower position, and'is held in such position-by a spring',m, which is aiiixed to the block o, on which' the rod, z', to which the'oat I is attached, slidesby meansotl the pins and slot, as shown at 1'.

"The said spring m catches above a-p in,1t, on the rod z', and thus prevents the oat I from rising,-and thereby closing the pipe C until the requisite quantity of water passes into the meter-tank.-

' When the water ,has riscn in tbe mctcr-tankhigh enough to enter the siphen I", the float G is buoyed up, and bymeans of the lever g, Yto which it is attached, bears awaythe spring m, as shown at`fig. 4, an'd permits the lient I tol rscand' close the gate d. l l

The iloat I isl held in its upper position by means of a pin, e, aiiixed to therod z', and spring #affixed to the block o, similarly to the springm before described. Y 4

When the oatI rises, from the buoyantcfi'ect of the water, the pin e catches in a hole in the said spring Z, thereby .holding the iioat', and consequently the gate d, closed, until the .water in the meter-tank has been dischargedbythc siphon I". i l v When this takes place, the float I-I, which is connected with the lcver c by a rod, h, causes the said lever tobear. ofi` the spring l and liberate the pin e, when the iioat I falls to its lower position, and, in falling, causes thebeiore-mentioned mechanism te openthe gate cl, and permit the water to again How from the pipe C.

'.lhe spring l is newl borne away from the pin e, and would not catch upon it as long as the lever c was so
